Pull Request Overview
Add MTP support for additional Garmin Descent models by centralizing model metadata and leveraging a shared model list in both the parser and device code.
- Introduce a
garmin_model_tstruct (including anmtp_capableflag) and declare a globalgarmin_modelsarray in the header. - Update
src/garmin_parser.cto use the sharedgarmin_modelsarray instead of a local static list. - Enhance MTP detection logic in
src/garmin.cto iterate overgarmin_modelsand skip non-MTP-capable devices.

- [nitpick] The loop index variable 'i' is not descriptive. Consider renaming it to something like 'model_index' for clarity.
unsigned i;
src/garmin.h:39
- Consider adding a comment explaining what the 'mtp_capable' flag represents and how it should be used, to improve code self-documentation.
bool mtp_capable;

Magic number 0x4000 is used to derive the USB product ID flag. Consider defining a named constant (e.g., USB_MTP_FLAG) to improve readability and maintainability.
